JOB OVERVIEW

## Position Summary

We are hiring a senior-level engineer to design, build, deploy, secure, and maintain websites and web applications for multiple businesses.

These websites will integrate directly with GoHighLevel for CRM, lead capture, pipeline management, scheduling, automation, messaging, and customer communication.

This is not a basic web design role.

This is not a virtual assistant position.

This is not a role for someone whose experience is limited to building pages inside GoHighLevel.

We need a true full-stack engineer who can build secure production systems and integrate them cleanly with GoHighLevel.

* Integrating websites with GoHighLevel through APIs, webhooks, forms, calendars, workflows, and custom fields
* Connecting website activity to GHL contacts, opportunities, pipelines, and automations
* Building custom integrations using REST APIs, JSON, webhooks, Zapier, or Make
* Deploying websites to production
* Configuring domains, DNS, SSL certificates, and hosting
* Monitoring uptime, performance, errors, and security

* Logging and security monitoring

Experience with one or more of the following is strongly preferred:

## Required GoHighLevel Capabilities

* SSL certificates
* Domain configuration
* Docker

## Multi-Client Environment Requirements

* Separate databases or secure data isolation
* Separate GHL sub-accounts
* Separate deployment environments
* Clear documentation
* Secure access controls
* No client data crossover
* Repeatable build and deployment standards

## Performance Expectations

You will be expected to:

* Build production-ready websites without constant supervision
* Diagnose problems independently
* Produce secure and maintainable code
* Deliver stable GHL integrations
* Document every system you build
* Communicate technical issues clearly
* Manage multiple business websites simultaneously
* Escalate only genuinely advanced architectural or security issues
* Verify that every deployment works before declaring it complete

## Automatic Disqualifiers

10. Desired hourly or monthly compensation
11. Availability during U.S. business hours

Applications missing required evidence will not be reviewed.

## Technical Assessment

Qualified candidates will be required to complete a practical assessment that may include:

* Building a secure login flow
* Implementing two-factor authentication
* Creating role-based access
* Connecting a website form to GoHighLevel
* Creating or updating a GHL contact

* Triggering a workflow through a webhook
* Deploying the application to a live environment
* Configuring SSL and DNS
* Documenting the complete solution

We are not hiring a page builder.
